Abstract
1,257,137. Lubricating. NECCHI S.p.A. 6 March, 1970 [7 March, 1969], No. 10908/70. Heading F2A. [Also in Divisions F1 and H2] An electrical motor/compressor unit has a shaft 19 mounted in a housing 17. A disc 31, attached to the shaft 19, is located adjacent a surface 32 of the housing, and when rotating, conveys lubricant 12 from a reservoir to a lubricant chamber 21, via an arcuate groove 34 which is formed in the surface 32. The groove 34 connects to the reservoir, via a cavity 22 and a hole 23 which are formed in the housing 17. Lubricant is gravity-fed through a duct 36 to a clearance 37 formed between a portion 78 of the shaft 19 and a bore 18 of the housing 17, and is conveyed, by means of grooves 39, 40 in the shaft, to the bearing surfaces. The groove 39 also conveys lubricant to a passage 41, lubricant then being collected by rotating fins 16 of a rotor 15 so as to be thrown on to stator coils 14 and effect cooling thereof. The groove 40 also conveys lubricant to a recess 42 which is formed between a portion 43 of the shaft 19 and the disc 31, the lubricant then passing through a horizontal hole 44 in a crank-pin 28 of the compressor and through a radial hole 45. Lubricant passes, through a groove 46 in the crank-pin, into a hole 47 in a connecting rod 27, and to a gudgeon-pin 26 so as to lubricate a piston 25 which reciprocates in a cylinder 24. The stator coils 14 are also cooled by means of lubricant which flows from the chamber 21, through an inclined duct 48 and on to another set of rotating fins 16. Refrigerant gas is sucked through the gap between the rotor 15 and the stator 13, issues into a recess 49, is passed to the cylinder 24, via a duct 50 and a valve (not shown), and has lubricant entrained therein.
